CVE-2026-70850 in Hyperion Financial Management
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Financial Management product of Oracle Hyperion (component: Security). The supported version that is affected is 11.2.25.0.000. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where Oracle Hyperion Financial Management executes to compromise Oracle Hyperion Financial Management. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hyperion Financial Management accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Financial Management. CVSS 3.1 Base Score 3.0 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L).

The identified vulnerability resides within the Security component of Oracle Hyperion Financial Management, specifically affecting version 11.2.25.0.000 and potentially other supported releases in that lineage. This flaw is classified as a difficult-to-exploit issue that requires an attacker to possess high-level privileges on the underlying infrastructure where the application executes. The nature of this vulnerability suggests a failure in proper access control or input validation mechanisms within the security subsystem, allowing authenticated users with elevated system rights to manipulate internal data structures or execution flows in unintended ways. Because exploitation demands significant preconditions such as local logon and high privilege levels, it is generally categorized under scenarios involving insider threats or compromised administrative accounts rather than remote network-based attacks.
From a technical perspective, the vulnerability enables unauthorized modifications to accessible data within the Oracle Hyperion Financial Management environment. This includes the ability to perform unauthorized updates, inserts, or deletes against critical financial records and configuration settings stored by the application. Such capabilities directly compromise the integrity of the system's data layer, potentially leading to inaccurate financial reporting, corrupted audit trails, or manipulation of sensitive business logic parameters. The presence of these write operations indicates that the security boundary between administrative functions and standard user operations may be insufficiently enforced at specific code paths within the security module, allowing privileged actions to bypass intended restrictions when triggered through this specific flaw.
In addition to integrity violations, the vulnerability poses a risk to system availability by enabling partial denial of service conditions. An attacker leveraging this weakness can cause disruptions that degrade the performance or responsiveness of Oracle Hyperion Financial Management services without necessarily taking the entire infrastructure offline. This partial degradation could manifest as increased latency, temporary unavailability of specific modules, or resource exhaustion resulting from malformed requests crafted using elevated privileges. The impact on availability underscores the importance of robust error handling and resource management within the application's security processing routines to prevent malicious actors from destabilizing operational continuity even when full system compromise is not achieved.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 3.0, reflecting low overall risk due to the high attack complexity and privilege requirements. The vector string (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L) confirms that the attack vector is local, requiring high complexity and high privileges for exploitation, with no user interaction needed once access is gained. While confidentiality impacts are absent in this specific assessment, the localized integrity and availability impacts remain significant for organizations relying on precise financial data processing. This aligns with Common Weakness Enumeration categories such as CWE-269 Improper Privilege Management or CWE-787 Out-of-bounds Write if memory corruption is involved, though the primary classification remains centered around unauthorized access leading to state modification.
Mitigation strategies should focus primarily on strict adherence to principle of least privilege and rigorous monitoring of administrative activities. Organizations must ensure that only essential personnel have high-level logon capabilities to the infrastructure hosting Oracle Hyperion Financial Management. Implementing comprehensive logging and anomaly detection systems can help identify unusual patterns of data manipulation or service degradation indicative of exploitation attempts. Additionally, applying all available security patches from Oracle is critical, as vendors typically address such flaws through updates that harden access controls and improve input validation within the affected components. Regular audits of user permissions and review of system logs for unauthorized write operations are essential defensive measures to maintain the integrity and availability of financial management systems against insider threats or compromised privileged accounts.
